Quarterback EJ Manuel and the Buffalo Bills offense have struggled the last few weeks. However, Day 2 of mini camp was one of the offense's better days.

Offensive coordinator Nate Hackett has given Manuel the keys to the car, and says the biggest thing for him now is "the command of the offense."

"I think with the system we have, there's a lot of responsibility on the quarterback to be able to run the whole thing, getting the guys lined up and communicating with everyone. We put a lot on him from that standpoint. How he operates the offense, how he commands it, and how he picks up the new stuff has been something we've really strived for and he's done a really nice job with it," Hackett said.

The Bills wrap up mini camp on Thursday, their last practice before training camp in July.
